Abstract

The invention concerns a sterilization container which is preferably intended for hospital waste and is formed by a bin (1) having a filler opening, which is delimited by the upper edge of the side wall (5) of the bin and is opposite the base (4) thereof, and a lid (2) for covering the filler opening. The bin (1), and possibly also the lid (2), consists of a tough plastics material which is permeable to microwaves and is still resistant to elongation above the boiling point of water. A pressure-tight sealing arrangement (20), disposed between the bin (1) and lid (2), and a closure arrangement (3, 29), for securing the lid (2) on the bin (1) against the effect of internal pressure in the bin (1), ensure that the contaminated waste collected in this waste-collection container can be sterilized when the container has been hermetically closed and the waste has been moistened by microwave radiation and then disposed of in the sterile state. Owing to the material from which it is constructed, the container withstands the internal pressure which builds up during this process.

Description

Sterilization vessel

Technical field

The invention relates to a sterilization container, in particular for hospital waste.

BACKGROUND OF THE INVENTION

Sterilization containers consist of a collection container whose upper opening can be closed with a lid and this collection container is primarily intended for hospital waste but may also serve other purposes, such as the manufacture of medicaments.

Contaminated wastes are usually sterilized by heating with steam. To this end, the waste must be supplied with a sufficient quantity of sufficiently hot steam, and it must be ensured that each part of the waste is sufficiently long and intensively exposed to steam to destroy all infectious germs. When hot steam is supplied, there is a danger that either contaminated air that has not been sufficiently heated or already cooled contaminated steam will penetrate into the environment.

Solutions based on the use of microwave radiation for waste sterilization have already emerged. If this waste is liquid, it can be heated by microwaves without problems, but it is necessary to ensure that even those layers of waste that are insufficiently exposed to radiation due to the inhomogeneity of radiation by heat exchange with the surrounding layers.

However, if the waste is wholly or partially dry, the microwaves are not suitable for heating. For this reason, it is expedient to moisten the waste so that sufficient water vapor is produced by evaporating the water so that the desired waste sterilization is desired. To achieve a sufficient vapor temperature, the waste must be placed in a pressure vessel in which, due to the increased internal pressure caused by the start of evaporation, the evaporation temperature is increased and then the vapor gas can no longer be heated by microwaves.

Thus, if microwave sterilization of waste is envisaged, pressure vessels should be used. However, these pressure vessels are usually very expensive and therefore using pressure vessels to collect waste prior to sterilization and to remove waste is not economical.

Handling contaminated waste before sterilization is very dangerous, and sterilized waste is still the living ground for the development of a variety of disease germs, so sterilized waste is best sent for incineration in a package that safely prevents any recurrence.

DE 38 33 281 C1 discloses a waste pressure vessel adapted to sterilize hospital waste by means of microwave radiation. DE 42 25 430 A1 discloses a device for disinfection or disinfection. sterilization of germ and bacterial waste. Here, the waste is placed in a container having a pivoting lid equipped with an airtight sealing ring, which is tightly closed and the waste is eventually moistened with water and subsequently exposed to microwave radiation.

It is an object of the present invention to provide a sterilization container which can collect, sterilize and incinerate contaminated waste in a simple and economical manner.

As used herein, terms such as top, bottom, up and down refer to the basic working position of the container when filling, with the bottom standing on the ground.

SUMMARY OF THE INVENTION

The aforementioned drawbacks are largely eliminated by the sterilization vessel of the present invention, which consists in that the sealing assembly between the collecting vessel and the lid consists of, in addition to the sealing ring, housed in the upper sealing groove in the lid and the lower annular groove in the collecting vessel. its shape, from still further sealing points on the collecting vessel and on the lid, further comprising a closure for urging the lid onto the collecting vessel against the internal pressure in the collecting vessel, the collecting vessel and lid being made of a rigid and boiling water resistant and stable, microwave-transmissive plastic.

The sterilization container according to the invention can be produced at the same cost as simple contaminated waste containers used up to now, but the container is able to reliably withstand the stresses and pressures generated by microwave sterilization and other handling. Even after sterilization, the waste can remain in the container without having to open it, and even after the vacuum has been generated inside the container, the container keeps its shape reliably. The closure prevents unwanted or accidental opening.

After the container has been filled and closed, it is no longer necessary to open the container until sterilized waste for incineration has been delivered and therefore, even in normal hospital operation, the container is not required to be opened and the closure can still be secured with an additional lock.

Preferred embodiments of the sterilization container according to the invention solve in particular light stacking of still empty collecting containers and lids in columns and furthermore increase the strength of the sterilization container, its secure sealing and ensuring a safe handling thereof.

In one preferred embodiment, an arrangement is provided that allows the clamping device to be securely seated on the collection container when the lid is not fitted. Thus, the closure cannot be lost. Depending on the position of the closure, it is also known at any time whether the collecting container is closed or not, even if the lid has already been fitted and whether additional waste can therefore be inserted.

In a preferred embodiment, a recess is formed in the central zone of the lid, the bottom of which has a thickness less than that of the other portions of the lid. The recess is suitably reinforced by ribs against deformation due to internal pressure in the container. The bottom thickness is so small that it can be punctured with a special needle and then with the needle supplied to dry waste the necessary water to wet it before exposure to the microwave.

The needle can either be left in the opening and clogged, or the resulting opening can be blocked in another way to ensure the tightness of the entire sterilization container. The present sterilization vessel has a circular cross-section, but the shape may be different.

DETAILED DESCRIPTION OF THE INVENTION

In FIG. 1, a collecting vessel 1 is shown in partial cross-section, the wall 5 of which consists of conical rings, which are tapered downwards and a transition shoulder 6 is formed between two adjacent rings 6. A bottom 4 is formed at the bottom of the collecting vessel 1. a rim of corner reinforcing ribs 7, the upper edge of which is horizontal, is formed inside the collecting container 1 at the transition between the wall 5 and the bottom 4.

The broken lines in FIG. 1 shows another bottom 4 and wall 5 of another collecting container which is inserted into the described container 1. As can be seen, the inner collecting container rests against the upper edge of the corner reinforcing ribs 7, respectively, by the edge of the bottom 4 and the wall 5 respectively.

In the middle of the bottom 4 there is a sleeve 8 which is cylindrical and protrudes downwards from the bottom. As can be seen from FIG. 1, the lower end of the sleeve 8 does not extend beyond the receiving lower plane of the collecting container 1. Between the bottom 4 and the wall 8 is located a ring of ribs 9.

At the second inset dashed line, the lower edge of which is spaced 1. The size of this rib spacing 7. This height is external in relation to the lower could not the walls 5 of the containers 1 do not clamp together.

side of the wall with the collecting hinder the collecting fig. 8, the container 1 in the handling of the container 1 also the container 1, which is also indicated to see the sleeve (connecting neck) 8, from the bottom 4 of the first collecting container is given by the height of the corner reinforcement determined so that all collars at 5 which will be described in detail they were above the top and could not be damaged or damaged. Cascadingly executed ensure that the walls 5 collecting

The upper side of the collection container 1 is closed by a lid 2, which is convex upwards. A cylindrical outer ring 10 is provided on the upper surface near the edge of the lid 2. The diameter of this ring 10 is determined to be slightly larger than the diameter of the bottom 4 of the collection container 1.

As can be seen from the other dashed contours at the top of the drawing, the other collection container, with its bottom 4 and the edge of the wall 5, can also be placed on a closed sterilization container with the lid 2 attached. The lower edge of the upper collection container sits inside the ring 10 to prevent it from slipping from age 2.

In the middle of the lid 2, a circular recess 11 is provided. In turn, near the outer periphery of the lid 2, there is provided an inner annular protrusion 12 whose inner surface is cylindrical but the outer one extends conically from below. Between the inner surface of the annular protrusion 12 and the outer surface of the annular recess, a plurality of bow-shaped reinforcing ribs 13 are arranged.

The center of the lid 2 surrounded by a circular depression 11 is provided with a axis 2 of the lid 2 with a coaxial circular groove 15 having a diameter such that the lower edge of the sleeve 8 above the other sterilization vessel lies therein when the sterilization vessel is under internal pressure. the sleeve 8 is also pressed slightly outwards. Inside the annular groove 15 a recess 14 is provided, the bottom of which is thinner than the other walls of the lid and the collecting container 1.

On the lower surface of the lid 2, a flange 16 is provided on the outer periphery, which abuts the collar 17 of the collecting vessel 1, which is provided on the outside of the wall 5 of the collecting vessel 1 below the upper peripheral edge. The clamping ring 3 is then externally fitted over the flange 16 and collar 17.

Turning now to FIG. 8, showing an enlarged detail VIII of FIG. 1. The elements mentioned above and their reference numbers and functions will not be repeated again. The flange 16 of the lid 2 and the collar 17 of the collecting container 1 have smooth contact surfaces facing each other, in which a flanged circular groove 19 is formed with a semicircular cross section on the flange side 16 and a collar circular groove 18 with a square cross section on the collector side collar 17. and both grooves have the same width.

As can be seen, the edges of the flange-shaped groove 19 are rounded in transition to the contact surface of the flange 16. The two annular grooves 18 and 19 together form a circular channel into which a sealing ring 20 of resilient material is inserted.

The two rounded edges of the flange groove 19 at the transition to the flange contact surface 16 form narrow channels for the sealing ring 20 on both sides, into which the material of the sealing ring 20 can bend when pressed between the flange contact surface 16 and the collar 17. formed by the circular grooves 18, 19 slightly lower than the height of the sealing ring 20 in the unloaded state, while the cross-sectional size of this channel corresponds to or slightly larger than that of the sealing ring 20.

On the outer periphery of the collar 17 of the collecting container 1, an upwardly facing collar 21 is formed, which tapers upwardly and which engages in a recess 16b formed on the outer periphery of the lid flange 16. it passes into the conical section 5b of the collecting vessel wall 5, which then continues upwards and the upper edge of the collecting vessel 1 is terminated by a rounding 5a.

The outer wall 22 of the lid 2 abuts the lower tapered section 22a on the conical wall section 5b of the collecting vessel 1. Above the tapered section 22a the outer wall 22 continues and passes into the annular projection 12 through a sealing groove 2a which is rounded and then the groove walls widen. As can be seen, the radius of the sealing groove 2a is greater than the radius of curvature 5a of the top of the wall 5. In addition, in the unloaded casing, the top of the wall 5 does not touch the sides of the circular groove 2a.

The upper surface of the flange 16 and the lower surface of the collar 17 converge away from the center of the sterilization container, and a clamping ring 3 is attached externally to the rigid connection of the flange 16 and the collar 17 whose inner cavity 23 corresponds to its shape to form a compressed flange 16 and collar 17 and the cavity 23 of the clamping ring 3 can then be easily fitted onto them. The clamping ring 3 will be described later.

When the clamping ring 3 is slid onto the outer surfaces of the flange 16 and the collar 17, it is sealed at several contact surfaces. On the one hand, the annular groove 2a between the outer wall 22 and the annular protrusion 12 and the rounding 5a of the wall 5 abut, the complementary tapered surfaces 22a of the outer wall 22 and the conical section 5b of the wall 5 abut against each other. 17 into a recess 16b formed on the outer circumference e of the flange 16 of the lid 2 and finally the sealing ring 20 is compressed in the annular channel between the flange 16 and the collar 17.

The narrow channels at the edge of contact of the circular grooves 18, 19 into which the gasket material 20 can bend when pressed between the flange contact surface 16 and the collar 17 will provide additional tightness even when the gasket is well gripped by the flange 16 and collar 17.

Due to the high internal pressure in the collecting vessel 1, it is possible that the upper part of the wall 5, which is located inside the annular groove 2a, extends outwards. In this case, only the upper edge of the wall 5 in the annular groove 2a is displaced and the gasket itself remains unchanged.

In order to prevent the collar 17 from deforming or deflecting from its position under load, a collar of reinforcing ribs, as shown in FIG. 8 dashed line.

On the outer periphery of the wall 5 of the collecting container 1, there are regularly placed four brackets 24 in the form of short protrusions and their position is again secured by cantilevering ribs 25 between them and the collecting container wall 5

In order to provide a better support for the collar 17, further connecting ribs 26 are provided between the collar 17 and the brackets 24. The position of the bracket 24 is particularly clear from FIG. Second

The clamping ring 3, the operating position of which is shown in FIG. 8, in the unattached state when the collecting container 1 is empty, can hang on the brackets 24, as shown by the dotted lines in FIG. 9. This fit ensures that the clamping ring is not lost and is always on hand even when the collection container 1 is empty. When the clamping ring 3 is in the operating position shown in FIG. 8, then the brackets 24 serve as handles to lift and handle the sterilization container. This prevents the full and heavy sterilization container from being handled by the gripping ring 3 attached, which could negatively affect the sealing of the sterilization container and lead to damage to the sealing elements.

In the variant shown in FIG. 9 it can be seen that the collar circular groove 18 in collar 17 is embodied as semicircular while the flange circular groove 19 in flange 16 is made as a shallow recess with a large radius so that the edges of the flange circular groove 19 are more distant from each other than the edges of the collar circular groove 18. This results in relatively spacious bays on both sides of the sealing ring 20, which can expand here when sealed by the clamping ring 2 and thus not prevent the flange 16 and collar 17 from contacting completely.

In FIG. 2 is a top view of the collection container 1. The corner reinforcing ribs 7 are well visible and one of the four brackets 24 is shown in dotted lines. It can be seen that the corner reinforcing ribs 7 are more numerous and these reinforce the connection of the outer wall 5 to the bottom 4 of the collection container 1 and thus stabilize the shape of the bottom of the collection container 1. In FIG. 3 is a top view of the lid 2, wherein a segment of the clamping ring 2 is also visible ·

The cross-section of the clamping ring 2 is best seen in FIG.

6. As shown in FIG. 4 and 6, on the outside of the clamping ring 2, alternately short reinforcing ribs 28 and long reinforcing ribs are therefore slightly stiff in the radial direction, so that the inner ribs 27 are elastic, but in the axial direction the cavity 23 is still shaped. stable.

In FIG. 4, 5 and 7, the closure can be seen. The clamping ring 2 is provided in one place with a radial groove 25. On both sides of the groove there are two hooks 22 »34 facing each other. Furthermore, a longitudinal projection is formed on the side of the groove where the hook 33 is spaced apart therefrom in which the longitudinal radial is formed. groove 35.

In the pulling lever 38 shown in FIG. 7, a retaining pin 20 is placed behind which the hook 23 hooks. The longitudinal rod 36, which can also be formed by two stacked ones and the pulling lever 38 comprising the flat pulling elements, is supported by the hook 34 pivotable on the pivot pin 21. supported by the swinging arm 38 via the pin 37.

When the pulling lever 38 deviates from the position shown in FIG. 7 with its free end in the horizontal direction from the clamping ring 2, then the path between the pivot pin 31 and the pulling pin 37 increases and both pins 20, 31 and thus both hooks 33, 34 are pushed together. The clamping ring 2 thus expands and can be pulled down from the flange 16 and the collar 17 and extend therethrough. When the pulling lever 38 is depressed again, the clamping ring 2 is pulled back to its clamping diameter. A possible extension of the clamping ring 3 in circumference compensates for the tolerances.

The pulling lever 38 has a hole (not shown) which coincides with the radial groove 35, so that both the opening and the radial groove 35 can be a cotter pin or a lock for securing the closing position of the pulling lever 38.

In FIG. 9, the pulling lever 38 is shown in section. The lever is made of rigid microwave-transmissive plastic. Fig. 5 is a view in the direction V of FIG. 4 and is a top view of the two hooks 33, 34 with the pulling lever 38 disengaged. FIG. 9, the pulling lever 38 is in section. All the holes and pins described above run parallel to the axis of the clamping ring 3, i.e. according to FIG. 1 in the vertical direction.

During storage, the sterilization containers are inserted into each other, as shown in FIG. 1. The clamping rings 3 are hung on brackets 24, 24, as shown in FIG. 9. The closure 29 of the clamping ring 2 is also closed. The clamping ring 3 is therefore at the collecting container and will not be lost, but does not interfere with the sufficiently high corner reinforcing ribs 7 when folding the containers together. The lids 2 are arranged separately, wherein the lid reinforcing ribs 13 of one lid abut the upper edge of the outer ring 10 above it. or an additional lid placed thereon 2.

First, the collection vessel 1 is removed from the stacked collection vessel stack and filled, for example, with hospital waste. Later, when it is filled, one lid 2 is again taken from the stored column of lids and is fitted with a sealing groove 2a on the peripheral edge of the open end of the collecting container 1. By means of the pulling lever 38 the clamping ring 3 is opened. The traction lever 38 is then pressed against the clamping ring 3, thereby fixing it.

Thus, the contents of the sterilization container are hermetically separated from the rest of the environment and sealed several times. Prior to sterilization, the thin-walled bottom of the lid 14 of the lid 2 can be pierced with a hollow needle and the necessary amount of liquid, e.g. water, inside the sterilization vessel, but it is also possible to pour water into the vessel before closing.

After sealing the injection site in a manner known per se, the sterilized container with the moistened contents is placed in a microwave chamber and exposed there to microwave radiation. Thereafter, the water in the vessel begins to evaporate until after some time the pressure has equalized with temperature. By steam evolution, the entire container is slightly dispensed, but the reinforcing ribs arranged at all dangerous points ensure constant sealing and dimensional stability of the sterilization container.

Microwaves can undergo heating and sterilization of the contents of the incinerator, while inside they can provide permanent reinforcing ribs.

After the contents have been burned and the container walls, if any, the container is sealed

After completion, taken to vacuum. Also in this and the shape stability of cleaning the container and lid, the sterilization container can be reused.
